TO ALLIS-CHALMERS MANUFACTURING COMPANY, A CORPORATION OF DELA- WARE.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Oct. 20, 1914.

Application tiled November 3Q, 1908. Serial No. 465,424.

T all wlafbm 'it may concern Be itknown that. I, 'JULES H. Hmr, a citi` zen'of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Producers, of whip improvement the following is a specification., I

My invention relates to improvements in apparatuses for producing gas.

The object of my invention is to produce a simple and efiicient apparatus capable of continuously producing gas high in carbon monoxid. I accomplish this object by means of the apparatus 'hereinafter more specifically described, reference being had to the accompanying drawings, forming part hereof, in Which--I Figure 1 is a vertical central section of my improved apparatus for making gas. Fig.'2 is a transverse section on line 2 2 of Fig. 1.

Referring to said drawings, l is a vertically disposed` furnace, preferably circular in cross section. The interior of said furnace is divided into two chambers 2 and 3, the lower one, 2, of which is preferably circular in cross section, and is provided with an opening-4 which is disposed tangentially relatively to the axis of the chamber, whereby when finely dividedcarbonaceous material is charged into said chamberit is caused to travel in a circulatory path so that the highly heated gases thereof meet the incoming material and raise the temperature thereof very considerably and vortex like the 4as ascends toward the contracted top of t e chamber and passes through the opening 5 into chamber 3. The process erein iA ly claimed in application Se- "T filed Feb: 1&1, 1910. The nfl the discharge of the e entrai `constricted open- .vent the escape of free ber, the particles being prevented from passing through the opening 5 by the action o centrifugal force thereon. A cap 5 in which passages a are formed is placed immediopening 5", and additionally the escape or' free carbon, i. any might be in the carbon monoxid admitted to chamber 3. Ata point in chamber Z where the highest temperature is attained, a'. c., where it begins to te pr contract a series of steam jets enter ports 6, 6 for the purpose of regulating or controlling the temperature of said chamber', whereby ,the usual refractory.v materials may be employed in the construction of the furnace, otherwise Without the introduction of the steam the temperature attained at this point in the furnace would quickly destroy the most highly refractory materials. The introduction of the steam at this point byl disassociating its hydrogen serves to produce a better quality of gas than is' usually obtained. The gas evolved is taken oiil through the openin 8 in the top of the .producer and-the slag rom the impurities contained in the material is removed through theopening 7,. The opening 4.- for the admission of carbonaceous malows, viz: The material admixedwith air sufficient to convert the same to carbon dioxid is charged into the furnace until the interior thereof becomes highly. heated,

preferably until the refractory lining becomes incandescent. The volume of air is then reduced to a volume sufficient only to convert the material into carbon monoxid,

and steam or other form of moisture is ad- Y mitted through ports 6, 6, for the purpose of controlling the very high temperature' sit-- tained and incidentally to enrich the gas evolved by disassociating hydrogen. he

highly heated material is given a circulatory motion due to the tangential disposition of the charging orifice and the pressure under which it is forced into the furnace and ascends in the form of a vortex toward the top of chamber 2, at the upper end of which, where thc highest temperature is attained, steam or other form of moisture is admitted which serves to preserve the furnace lining as heretofore stated. l

Having described my invention, what I claim and desire to secure by Letters Patent is 1. In a gas producer, a furnace compristing two superposed chambers, a single diaphragm extending entirely across andbetween said chambers, said diaphragm having a constricted central means o communication between said chambers, a fuel inlet to the lower chnuiber directed at an oblique :ingle to the wall of Suid chamber, and 'an opening from the upper chamber for the delivery of gas therefrom.

2. In n gas producer, e .furnace comprising two superpoScd chambers, a wall between said chambers having a cent-ral means o1 eomn'iunication between said chambers, an inlet for gus forming material at the lower end of the lower chamber directed at an oblique angle to the wall of said chamber, an inlet for moisture 'at the upper end of the lower chamber und adjacent said intermediate well, and an opening from the upper.

chamber for delivering gas therefrom.

In' a gas producer, a furnace comprising a chamber having an inlet thereto directed at an oblique angle to a wall of said chamber, and a single diaphragm extending entirely across the upper end of said chamber and provided with a constricted central outlet for gases therefrom for all conditions of operation of said gas producer.

4. In a gas producer, a furnace consisting of two superposed chambers separated by a.

single diaphragm und having a central con- Stricted means of communication, a fuel inlet leading to the lower end of the lower chamber and directed at an oblique angle to the well of said chamber, and a gas oftake leading from the upper end of the upper chamber.

'Suid inlets being directed et :in ohliquo'angle to the wall of saidchaniler, :ind a gas oftalre leading from the .upper end of the upper chamber. Qi 2;"

In testimony whereof, I have hereunto signed my name in the presence of two suh- Scribing witnesses.
